The optical transceiver can convert the electrical signal we want to transmit into an optical signal, and convert the received optical signal into an electrical signal and input it to our receiving end.
How the fiber optic transceiver works
Glass (or plastic) filaments (fibers) are used in fiber optic technology to transmit data. The use of fiber optic technology is based entirely on the principle of total internal reflection. The reflection or refraction of light depends entirely on the angle at which it intersects the plane. Fiber optic systems are very similar to copper core wire systems. The difference is that the fiber uses light pulses to transmit information along the fiber line, while the copper wire uses electronic pulses to transmit information along its own line.
The principle of the optical transceiver is to exchange the short-distance twisted pair electrical signal and the long-distance optical signal. The optical fiber transceiver utilizes the advantages of large information capacity, good confidentiality, light weight, small size, no relay, long transmission distance, etc., and solves the problem of Ethernet transmission. It is well used in the actual network environment where the Ethernet cable cannot be covered and the fiber must be used to extend the transmission distance.
The schematic of the fiber transceiver is given below:
Network fiber optic transceivers - widely used for their advantages of large information capacity, good confidentiality, light weight, small size, no relay, long transmission distance, etc. Optical fiber transceivers utilize the high-speed propagation medium of optical fiber. A good solution to the problem of Ethernet transmission. According to the fiber, it can be divided into multimode fiber transceivers and single mode fiber transceivers.
Multimode MM fiber: It has a large cable core bundle that allows hundreds of rays to propagate through the fiber at the same time. Multimode fiber is mainly used in short-distance systems (less than 2km).
Single mode SM fiber: It has a much smaller cable core bundle and only one beam can be transmitted through the cable core bundle. The single-mode fiber is designed to maintain the spatial and spectral integrity of each optical signal over long distances for more information to be transmitted.
Modem selection of multimode fiber modems and single mode fiber modems: Modem prices for single mode fiber are generally slightly higher than modem mode (moden) prices, but due to the current single mode The use of optical fiber is becoming more and more widespread, and the price of single-mode fiber is greatly reduced. Now it is lower than the price of multimode fiber. If the transmission distance is not very long, it is recommended to use a multimode fiber modem (moden), but If the distance exceeds a certain distance, it is recommended to use a single mode fiber modem (m), because the price of the entire system can be reduced.

Nowadays, many companies like to buy PVC soft-curtain high speed rolling doors when purchasing PVC fast-rolling doors. What are the characteristics and advantages of it that make everyone love it? Let's talk about the overall advantages of PVC fast roller shutter doors.

Features and advantages of PVC fast roller shutter doors:

1.Good UV protection effect of PVC fast roller shutter door

The UV-proof door curtain of PVC fast rolling door, as the screen of the welding welding area, can filter harmful UV rays through the scenery, which is convenient for viewing the working situation, and prevents the flying and diffusion of sparks, smoke, debris, etc., to protect the safety of personnel. prevent fire.

Sound insulation effect PVC fast roller shutter door curtain can reduce noise decibels, prevent noise diffusion, reduce noise pollution, and be used as a machine compartment screen to improve the sound insulation effect of operations.

2. Good cold resistance effect of PVC fast roller shutter door

In the case of low temperature, the PVC fast rolling shutter can still maintain a high degree of softness, making it convenient for people and vehicles to enter and exit, and has a good isolation effect. It can prevent the loss of air conditioning and heating to a greater extent and save energy.

3. Good airtight performance of PVC fast roller shutter doors

A sealing strip with better sealing performance is installed in the track of the fast roller shutter door. With the weight of the door curtain itself, it will not bend and affect the normal operation under the wind speed of the harsh weather.

4. Good thermal insulation and energy saving effect of PVC fast roller shutter doors

PVC fast rolling shutter not only consumes no electricity, has no noise, no moving components, improves freezing efficiency, but also reduces the number of revolutions of the freezer, saving up to 50% of electricity.


5. Good anti-static effect of PVC fast roller shutter door

The curtain of the PVC fast rolling door does not produce static electricity after friction, which is suitable for the factory effect where static electricity is strictly prohibited.

Widely used in office buildings, public buildings, hotels, hospitals, supermarkets and factories in Asia, Eastern Europe and Africa. The specific requirements of an effective door system in different situations (eg clean room, operating room) may vary in different parts of the world.
